Hello I'm new on the list and with ocaml (and sdl-ocaml of course). And my first question: I need an example for generate a 2d opengl texture from a sdl surface. Exactly my probleman is the function GlTex.image2d I don't know how to send the image pixels, may be GlPix.create? :-/ Another question, i cannot view mailing list archives from the link of the web, it's usual? Thanks!!!!! |

Exactly my probleman is the function > GlTex.image2d I don't know how to send the image pixels, may be > GlPix.create? :-/ There's the Sdlgl.to_raw function : to_raw : Sdlvideo.surface -> [`ubyte] Raw.t It converts (without copying) a SDL surface into a LablGL Raw buffer. LablGL provides functions (such as GlPix.of_raw) for converting these buffers into GL textures. I attached an example. The code (by Jean-Christophe Filliatre) is translated from an OpenGL tutorial : http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=06 > Another question, i cannot view mailing list archives from the link > of the web, it's usual?
